This week Canadian observers reported rubythroat and rufous hummingbirds arriving together. Their locations mark the spot where the two species meet at the end of their migration trails.

"Rufous showed early morning to the feeder and about an hour later a rubythroat arrived." Egremont, Alberta, Canada 05/27/14

Where did my hummers go?This spring you watched the migration maps, got your feeders ready, and watched the hummingbirds' return with great excitement. Now it's early-June and it seems they've virtually disappeared.

"I live between DC and Baltimore. I had a male and female visit my feeders in early May for two weeks. Since then nothing." Laurel, Maryland 06/01/14

Hummingbird expert Lanny Chambers says this happens each year. Now is the time when females are tending to nests, often built in secluded areas. Their chicks need a diet of high protein insects and spiders, so females often leave the feeders to the males during this time.

Explore: Nectar Sources

The natural nectar in flowers provides a portion of the food many hummingbirds rely on. This nectar is composed mainly of sugars (sucrose, glucose, and fructose) and water with a tiny amount of protein. Here is a small selection of the kinds of flowers you've reported as nectar sources for hummingbirds.
